Upon completion of all the tests, press “Results”. The window with test results (Fig.14) will appear.

In case one of the test results is negative, the fault should be found and eliminated. After this,
the test procedure must be run again.
3. POST-MAINTENANCE RUN OF A COMPRESSOR
When the compressor has been repaired and some of its moving parts have been replaced, its
post-maintenance run is necessary. Otherwise, the grit resulted from the components wear will
inevitably damage the system.
A post-maintenance run of the compressor includes the following steps:
1. Add 20-30g of diagnostic oil (PAG46yf) into the compressor.
2. Fix the compressor on the mounting face of the bench (Item 2.3).
3. Select «Manual mode». Make the test bench settings as shown in Fig.29. Set the level of the
PWM signal on the electromagnetic valve as 100%.
